Abstract
PURPOSE We hope that by analyzing the clinical features of cerebral venous sinus thrombosis (CVST), we can help ophthalmologists reduce misdiagnosis or delayed diagnosis. DESIGN We evaluated 47 patients with CVST in terms of clinical manifestations. METHODS All cases were analyzed in terms of risk factors, clinical symptoms, ophthalmic examination, imaging examination and lumbar puncture. RESULTS The body mass indices (BMIs) of 41 patients (87.2%; 95% CI, 77.7-96.8%) were≥24, which is overweight by Chinese standards. There were 22 patients (46.8%; 95% CI, 32.5-61.1%) with BMIs≥28, who were considered obese. Thirteen were hypertensive (27.7%; 95% CI, 14.9-40.5%). The initial symptoms included blurred vision (23, 48.9%; 95% CI, 34.6-63.2%), amaurosis fugax (13, 27.7%; 95% CI, 14.9-40.5%), headache (11 patients, 23.4%; 95% CI, 11.3-35.5%), dizziness (3, 6.4%; 95% CI, -0.6-13.4%), and bilateral diplopia (3, 6.4%; 95% CI, -0.6-13.4%). There were 9 patients (9, 19.2%; 95% CI, 7.9-30.4%) with blindness, 23 patients (48.9%; 95% CI, 34.6-63.2%) with pupillary abnormalities, and 40 patients (85.1%; 95% CI, 74.9-95.2%) with papilledema. Forty-three of the 45 patients who successfully underwent a routine lumbar puncture showed high intracranial pressure (91.7%; 95.6% CI, 89.6-101.6%). Finally, two cases are reported in greater detail for illustrative purposes. CONCLUSION The main reasons interfering with the diagnosis of CVST might be its nonspecific ocular symptoms and the physicians' clinical thought process being limited to the scope of common ophthalmological diseases.

Abstract
Nitrogen fertilization can promote rice yield but decrease resistance to sheath blight (ShB). In this study, the nitrate transporter 1.1b (nrt1.1b) mutant that exhibited less susceptibility to ShB but without compromising yield under NH4+ fertilization was screened. NRT1.1B's regulation of ShB resistance was independent of the total nitrogen concentration in rice under NH4+ conditions. In nrt1.1b mutant plants, the NH4+ application modulated auxin signaling, chlorophyll content, and phosphate signaling to promote ShB resistance. Furthermore, the findings indicated that NRT1.1B negatively regulated ShB resistance by positively modulating the expression of H+-ATPase gene OSA3 and phosphate transport gene PT8. The mutation of OSA3 and PT8 promoted ShB resistance by increasing the apoplastic pH in rice. Our study identified the ShB resistance mutant nrt1.1b, which maintained normal nitrogen use efficiency without compromising yield.

Abstract
OBJECTIVE This study aimed to explore the modulatory effects of menopause hormone therapy (MHT) on mood disorders among postmenopausal women. METHODS A cross-sectional study was conducted to recruit postmenopausal women, including patients (arranged MHT for over 3 years as the medication group) and non-MHT controls. All participants were asked to respond to the Center for Epidemiological Studies Depression Scale (CES-D) and Generalized Anxiety Disorder Screener (GAD-7) questionnaires to assess their depression and anxiety status. RESULTS A total of 230 cases from the two groups were determined based on propensity score matching analysis by matching the menopausal age and menopausal durations. We found that MHT served as a favorable modulator in the depression status of postmenopausal women. Among the four factors of the CES-D questionnaire, our data indicated that the differences between the two groups fell primarily into two aspects: depressive emotion, and somatic symptoms or retarded activities. MHT was mainly involved in improving the depression of overweight women. However, no substantial effects of MHT were observed on the regulation of anxiety. CONCLUSION Postmenopausal women, especially the overweight population, who have experienced MHT exhibited an improved depressive status but not their anxiety condition.

Abstract
Superior mediastinal lymph node metastases in papillary thyroid cancer are uncommon. The clinical characteristics and surgical strategy of superior mediastinal lymph node metastases remain unclear. Superior mediastinal lymphadenectomy can be accomplished either by a transcervical or transsternal approach. Transsternal approach for superior mediastinal lymphadenectomy can cause great damage; transcervical approach sometimes results in inadequate exposure. Here we report our experience of a papillary thyroid cancer patient with superior mediastinal lymph node metastases who underwent video-assisted superior mediastinal lymphadenectomy. A 49-year-old woman diagnosed with papillary thyroid cancer in left thyroid underwent unilateral lobectomy and ipsilateral central and lateral node dissection in the local hospital 4 years ago. Currently lymph node metastases were found in mediastinum and the right neck, some of which were adjacent to the right innominate vein. Unilateral lobectomy, ipsilateral central and lateral node dissection, and video-assisted superior mediastinal lymphadenectomy were successfully performed by transcervical approach. Subsequently, the patient received thyroxine suppression therapy and adjuvant radioiodine treatment. Video-assisted superior mediastinal lymphadenectomy, providing adequate exposure for a complete superior mediastinal lymphadenectomy, is proved to be safe and feasible.

Abstract
Background Rice sheath blight, which is caused by Rhizoctonia solani, is the most destructive disease affecting rice production, but the resistance mechanism to this pathogen has not been fully elucidated. Results In this study, we selected two rice cultivars based on their resistance to the pathogen and analyzed and compared the transcriptomic profiles of two cultivars, the moderately resistant variety Gangyuan8 and the highly susceptible variety Yanfeng47, at different time points after inoculation. The comparative transcriptome profiling showed that the expression of related genes gradually increased after pathogen inoculation. The number of differentially expressed genes (DEGs) in Yanfeng47 was higher than that in Gangyuan8, and this result revealed that Yanfeng47 was more susceptible to fungal attack. At the early stage (24 and 48 h), the accumulation of resistance genes and a resistance metabolism occurred earlier in Ganguan8 than in Yanfeng47, and the resistance enrichment entries were more abundant in Ganguan8 than in Yanfeng47. Conclusions Based on the GO and KEGG enrichment analyses at five infection stages, we concluded that phenylalanine metabolism and the jasmonic acid pathway play a crucial role in the resistance of rice to sheath blight. Through a comparative transcriptome analysis, we preliminarily analyzed the molecular mechanism responsible for resistance to sheath blight in rice, and the results lay the foundation for the development of gene mining and functional research on rice resistance to sheath blight.

Abstract
Aspergillus versicolor, a widely distributed fungus, is associated with pollution and carcinogenic hazards. This study aimed to examine the functions of the A. versicolor exudate and laid a scientific foundation for improving our understanding, utilization, and control of A. versicolor. The A. versicolor exudate proteome, ion content, and amino acid components were determined using label-free quantitation, atomic absorption spectrophotometry, and high-performance liquid chromatography, respectively. In total, 502 proteins were identified in the A. versicolor exudate. Gene Ontology, Kyoto Encyclopedia of Genes and Genomes, and cluster of orthologous group analyses were used to annotate the functional classification and pathways of the aligned proteins. Proteins identified in the exudate were mainly enriched in carbohydrate metabolic process, translation, oxidoreductase activity, oxidoreductase activity, hydrolase activity, cell wall-related processes, catalytic activity, and unknown functions. The exudate comprised Na, K, Ca, Fe, and Mg cations. Among the 17 types of amino acids detected in the exudate, 7 were essential and 10 were nonessential. The exudate may be involved in the vital processes of A. versicolor. Additionally, the exudate may play an important role in the growth, development, reproduction, homeostasis, nutrient supply for regrowth, and virulence of A. versicolor.

Abstract
Objectives This work aimed to study the influences of carbonated beverages (CBs) on the testis growth and the expression levels of androgen receptor (AR) of mice. Methods Two experimental groups of 30 mice each PEP-1 and PEP-2 drank 50% and 100% Pepsi-Cola, respectively for 15 days. Other 2 experimental groups of 30 mice each COC-1 and COC-2 drank 50% and 100% Coca-Cola, respectively for 15 days. The control group (CG) of 30 mice drank water. Bilateral testes were harvested aseptically on days 0, 5, 7, 10, 13 and 15. Real-time PCR and Western blot were implemented to detect levels of androgen receptor (AR) mRNA and protein in testis tissues. Results Testes masses of PEP-2, COC-1 and COC-2 were greater than those of PEP-1 and CG (P < 0.05). On day 15, testis longitudinal diameter (TLD) of CBs-treated mice was increased as compared to CG. TLD, testes transverse diameters (TTD) and AR proteins levels of PEP-2 and COC-2 were increased in comparison with CG (P<0.05). Serum testosterone concentrations of PEP-2 were higher than that of COC-1 and CG (P < 0.05). Levels of AR mRNAs of four CBs-treated mice were increased by 60.18%, 67.26%, 65.93% and 78.76%. Conclusions A high concentration of Coca-Cola and Pepsi-Cola could raise TLD and TDD, enhance testosterone secretion, and increase serum EGF concentrations.

Abstract
BACKGROUND With global warming, soil seed banks at high altitudes face dual challenges, excessive water absorption and thinner snow cover that increase underground temperature. A better understanding of freezing tolerance of hydrated seeds provides insights for conservation in natural soil seed banks. OBJECTIVE To understand the adaptation mechanisms of seed freezing tolerance under various climates, in relation to cooling rate and seed size. MATERIALS AND METHODS Twelve ecotypes of lettuce (Lactuca sativa) seeds were collected from different geographical locations around the world. Seeds were fully hydrated and tested for their freezing tolerance using programmed cooling methods. RESULTS The size of seeds from different climate regions varied, and was correlated with the freezing tolerance of the hydrated seeds (P < 0.05). Larger seeds showed poorer freezing tolerance. The local climates of maternal plants were also well correlated to seed freezing tolerance (P < 0.05), especially under slow cooling conditions. The seeds collected in regions with high spring rainfall exhibited greater freezing tolerance. CONCLUSION Freezing tolerance of hydrated seeds is affected by the climate of maternal plants and by seed size. Our data revealed the existence of an adaptation mechanism of freezing tolerance among various ecotypes of lettuce seeds. doi.org/10.54680/fr22410110412.

Abstract
BACKGROUND Rice sheath blight, caused by Rhizoctonia solani Kühn (teleomorph: Thanatephorus cucumeris), is one of the most severe diseases in rice (Oryza sativa L.) worldwide. Studies on resistance genes and resistance mechanisms of rice sheath blight have mainly focused on indica rice. Rice sheath blight is a growing threat to rice production with the increasing planting area of japonica rice in Northeast China, and it is therefore essential to explore the mechanism of sheath blight resistance in this rice subspecies. RESULTS In this study, RNA-seq technology was used to analyse the gene expression changes of leaf sheath at 12, 24, 36, 48, and 72 h after inoculation of the resistant cultivar 'Shennong 9819' and susceptible cultivar 'Koshihikari' with R. solani. In the early stage of R. solani infection of rice leaf sheaths, the number of differentially expressed genes (DEGs) in the inoculated leaf sheaths of resistant and susceptible cultivars showed different regularity. After inoculation, the number of DEGs in the resistant cultivar fluctuated, while the number of DEGs in the susceptible cultivar increased first and then decreased. In addition, the number of DEGs in the susceptible cultivar was always higher than that in the resistant cultivar. After inoculation with R. solani, the overall transcriptome changes corresponding to multiple biological processes, molecular functions, and cell components were observed in both resistant and susceptible cultivars. These included metabolic process, stimulus response, biological regulation, catalytic activity, binding and membrane, and they were differentially regulated. The phenylalanine metabolic pathway; tropane, piperidine, and pyridine alkaloid biosynthesis pathways; and plant hormone signal transduction were significantly enriched in the early stage of inoculation of the resistant cultivar Shennong 9819, but not in the susceptible cultivar Koshihikari. This indicates that the response of the resistant cultivar Shennong 9819 to pathogen stress was faster than that of the susceptible cultivar. The expression of plant defense response marker PR1b gene, transcription factor OsWRKY30 and OsPAL1 and OsPAL6 genes that induce plant resistance were upregulated in the resistant cultivar. These data suggest that in the early stage of rice infection by R. solani, there is a pathogen-induced defence system in resistant rice cultivars, involving the expression of PR genes, key transcription factors, PAL genes, and the enrichment of defence-related pathways. CONCLUSION The transcriptome data revealed the molecular and biochemical differences between resistant and susceptible cultivars of rice after inoculation with R. solani, indicating that resistant cultivars have an immune response mechanism in the early stage of pathogen infection. Disease resistance is related to the overexpression of PR genes, key transcriptome factors, and PAL genes, which are potential targets for crop improvement.

Abstract
OBJECTIVES To assess the clinical utility of prenatal chromosomal microarray analysis (CMA) in fetuses with abnormal renal sonographic findings, and to evaluate the association of pathogenic or likely pathogenic copy number variants (P/LP CNVs) with different types of renal abnormality. METHODS This was a retrospective study of fetuses at 14-36 weeks screened routinely for renal and other structural abnormalities at the Maternal and Child Health Hospital of Guangxi Zhuang Autonomous Region. We retrieved and analyzed data from fetuses with abnormal renal sonographic findings, examined between January 2013 and November 2019, which underwent CMA analysis using tissue obtained from chorionic villus sampling (CVS), amniocentesis or cordocentesis. We evaluated the CMA findings according to type of renal ultrasound anomaly and according to whether renal anomalies were isolated or non-isolated. RESULTS Ten types of renal anomaly were reported on prenatal ultrasound screening, at a mean ± SD gestational age of 24.9 ± 4.8 weeks. The anomalies were diagnosed relatively late in this series, as 64% of cases with an isolated renal anomaly underwent cordocentesis rather than CVS. Fetal pyelectasis was the most common renal ultrasound finding, affecting around one-third (34.32%, 301/877) of fetuses with a renal anomaly, but only 3.65% (n = 11) of these harbored a P/LP CNV (comprising: isolated cases, 2.37% (4/169); non-isolated cases, 5.30% (7/132)). Hyperechogenic kidney was found in 5.47% (n = 48) of fetuses with a renal anomaly, of which 39.58% (n = 19) had a P/LP CNV finding (comprising: isolated cases, 44.44% (16/36); non-isolated cases, 25.00% (3/12)), the highest diagnostic yield among the different types of renal anomaly. Renal agenesis, which accounted for 9.92% (n = 87) of all abnormal renal cases, had a CMA diagnostic yield of 12.64% (n = 11) (comprising: isolated cases, 11.54% (9/78); non-isolated cases, 22.22% (2/9); unilateral cases, 11.39% (9/79); bilateral cases, 25.00% (2/8)), while multicystic dysplastic kidney (n = 110), renal cyst (n = 34), renal dysplasia (n = 27), crossed fused renal ectopia (n = 31), hydronephrosis (n = 98), renal duplication (n = 42) and ectopic kidney (n = 99) had overall diagnostic rates of 11.82%, 11.76%, 7.41%, 6.45%, 6.12%, 4.76% and 3.03%, respectively. Compared with the combined group of CMA-negative fetuses with any other type of renal anomaly, the rate of infant being alive and well at birth was significantly higher in CMA-negative fetuses with isolated fetal pyelectasis or ectopic kidney, whereas the rate was significantly lower in fetuses with isolated renal agenesis, multicystic dysplastic kidney or severe hydronephrosis. The most common pathogenic CNV was 17q12 deletion, which accounted for 30.14% (22/73) of all positive CMA findings, with a rate of 2.51% (22/877) among fetuses with an abnormal renal finding. Fetuses with 17q12 deletion exhibited a wide range of renal phenotypes. Other P/LP CNVs in the recurrent region that were associated with prenatal renal ultrasound abnormalities included 22q11.2, Xp21.1, Xp22.3, 2q13, 16p11.2 and 1q21, which, collectively, accounted for 2.17% (19/877) of the fetuses with prenatal renal anomalies. CONCLUSIONS In this retrospective review of CMA findings in a large cohort of fetuses with different types of renal ultrasound abnormality, the P/LP CNV detection rate varied significantly (3.03-39.58%) among the different types of kidney anomaly. Our data may help in the decision regarding whether to perform prenatal genetic testing in fetuses with renal ultrasound findings. Specifically, prenatal CMA testing should be performed in cases of hyperechogenic kidney, regardless of whether or not the anomaly is isolated, while it should be performed postnatally rather than prenatally in cases of fetal pyelectasis. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
Autonomous robotic surgery has the potential to provide efficacy, safety, and consistency independent of individual surgeon's skill and experience. Autonomous anastomosis is a challenging soft-tissue surgery task because it requires intricate imaging, tissue tracking, and surgical planning techniques, as well as a precise execution via highly adaptable control strategies often in unstructured and deformable environments. In the laparoscopic setting, such surgeries are even more challenging because of the need for high maneuverability and repeatability under motion and vision constraints. Here we describe an enhanced autonomous strategy for laparoscopic soft tissue surgery and demonstrate robotic laparoscopic small bowel anastomosis in phantom and in vivo intestinal tissues. This enhanced autonomous strategy allows the operator to select among autonomously generated surgical plans and the robot executes a wide range of tasks independently. We then use our enhanced autonomous strategy to perform in vivo autonomous robotic laparoscopic surgery for intestinal anastomosis on porcine models over a 1-week survival period. We compared the anastomosis quality criteria-including needle placement corrections, suture spacing, suture bite size, completion time, lumen patency, and leak pressure-of the developed autonomous system, manual laparoscopic surgery, and robot-assisted surgery (RAS). Data from a phantom model indicate that our system outperforms expert surgeons' manual technique and RAS technique in terms of consistency and accuracy. This was also replicated in the in vivo model. These results demonstrate that surgical robots exhibiting high levels of autonomy have the potential to improve consistency, patient outcomes, and access to a standard surgical technique.

Abstract
Sheath blight (ShB) is one of the most common diseases in rice that significantly affects yield production. However, the underlying mechanisms of rice defense remain largely unknown. Our previous transcriptome analysis identified that infection with Rhizoctonia solani significantly induced the expression level of SWEET2a, a member of the SWEET sugar transporter. The sweet2a genome-editing mutants were less susceptible to ShB. Further yeast-one hybrid, ChIP, and transient assays demonstrated that WRKY53 binds to the SWEET2a promoter to activate its expression. WRKY53 is a key brassinosteroid (BR) signaling transcription factor. Similar to the BR receptor gene BRI1 and biosynthetic gene D2 mutants, the WRKY53 mutant and overexpressor were less and more susceptible to ShB compared to wild-type, respectively. Inoculation with R. solani induced expression of BRI1, D2, and WRKY53, but inhibited MPK6 (a BR-signaling regulator) activity. Also, MPK6 is known to phosphorylate WRKY53 to enhance its transcription activation activity. Transient assay results indicated that co-expression of MPK6 and WRKY53 enhanced WRKY53 trans-activation activity to SWEET2a. Furthermore, expression of WRKY53 SD (the active phosphorylated forms of WRKY53) but not WRKY53 SA (the inactive phosphorylated forms of WRKY53), enhanced WRKY53-mediated activation of SWEET2a compared to expression of WRKY53 alone. Taken together, our analyses showed that R. solani infection may activate BR signaling to induce SWEET2a expression via WRKY53 through negative regulation of ShB resistance in rice.

Abstract
Zinc (Zn) deposition in egg yolk is essential for the rapid growth and complete development of the avian embryo. Thus, it is crucial to obtain maximal Zn mobilization at an appropriate time during development in favor of the survival of avian embryos. The aim of this study was to study the developmental change of Zn mobilization and gene expression related to key Zn transport proteins between the yolk sac membrane and embryonic liver from the incubation d 17 (E17) to d 32 (E32) during duck embryonic developing. The weights of duck embryo, embryo without yolk sac, and embryonic liver increased as well as the yolk sac weight decreased linearly (P < 0.0001) when incubation day increased. The Zn concentration in the yolk sac did not change from E17 to E29 and only declined significantly from E29 to E32 of duck embryos, while hepatic Zn level decreased linearly as with the increased incubation time (P < 0.01). When the incubation day increased, the decreased Zn amount in the yolk sac and the increased Zn amount in the embryonic liver were observed (P < 0.0001). The calculated transfer-out rate of Zn in the yolk sac and transfer-in rate of Zn in livers were both increased from E23-26 to E29-32 (P < 0.01). Among E17, E23 and E29, the solute carrier family 39 member (ZIP) of ZIP10, ZIP13, and ZIP14 genes mRNA expressions were increased in yolk sac membrane but were decreased in the embryonic liver, while metallothionein 1 mRNA expression was increased both in the yolk sac membrane and liver (P < 0.05). In conclusion, yolk sac membrane and embryonic liver tissues displayed the similar developmental patterns of Zn mobilization and metallothionein 1 mRNA expression from E17 to E32 during duck embryonic developing. The appropriate time of the maximal rate of Zn mobilization were observed between E29 and E32 of duck embryo, associated with the significant changes of gene expression related to some key Zn transport proteins on E29 in yolk sac membrane and liver tissues.

Abstract
Abstract
Background
For the results of randomized controlled trials (RCTs) to be generalizable, they should report on and include the broad range of patients who have the disease.
Purpose
We assessed temporal trends and trial factors associated with 1) the reporting of race or ethnicity data and 2) the enrolment of Black, Indigenous, and people of colour (BIPOC) in Heart Failure (HF) RCTs.
Methods
We searched MEDLINE, EMBASE, and CINAHL for RCTs that recruited adults with HF and were published in journals with an impact factor ≥10 between January 1, 2000 and June 17, 2020. We extracted data in duplicate and used the Cochran-Armitage and Jonchkeere-Terpstra tests to examine temporal trends. We used multivariable regression to assess the independent association between trial factors and the outcomes of interest.
Results
A total of 414 RCTs met inclusion criteria, of which a vast majority (90.6%; 95% CI 87.4–93.2%) were coordinated in either Europe or North America. Only 157 of the 414 RCTs (37.9%; 95% CI 33.2–42.8%) reported race/ethnicity data; among the 158,200 participants in these trials, only 29,512 (18.7%; 95% CI 18.5–18.9%) were BIPOC. There was a significant increase in the reporting of race or ethnicity data (from 26.9% in 2000–2001 to 54.2% in 2019–2020, p<0.001) and in enrollment of BIPOC (from 16.5% in 2000–2001 to 23.9% in 2019–2020, p=0.038) between 2000–2020. Trial leadership by a woman was associated with twice the adjusted odds of reporting of race or ethnicity data (OR 2.0; 95% CI 1.1–3.8; p=0.028) and an 8.4% (95% CI 1.9–15.0%; p=0.012) adjusted increase in enrollment of BIPOC. The race/ethnicity of trial leaders was not available for analysis.
Conclusions
Among HF RCTs published between 2000–2020, <38% reported data on race or ethnicity, although this increased over time. Among trials reporting such data, <19% of participants were BIPOC, with modest increases in enrollment over time. Trials led by women had greater adjusted odds of reporting race/ethnicity data and enrollment of BIPOC.

Abstract
Abstract
Aims
Heart Failure (HF) has a disproportionate burden in low- and middle-income countries. The geographic representation of those who lead HF randomized clinical trials (RCTs) may not reflect the geographic burden of disease. We assessed temporal trends and trial characteristics associated with leadership outside Europe and North America, and explored whether there was a geographic association between trial leadership and participant enrolment.
Methods and results
We searched MEDLINE, EMBASE, and CINAHL for HF RCTs published in journals with an impact factor ≥10 between January 1, 2000, and June 17, 2020. We used the Jonckheere-Terpstra test to assess temporal trends and multivariable logistic regression models to determine associations between predictor and outcome variables.
There were 414 eligible RCTs. Only 80 of 828 trial leaders (9.7%; 95% CI: 7.8% to 11.8%), and 453 of 4656 collaborators (9.7%; 95% CI: 8.8% to 10.6%) were from regions outside Europe and North America, with no temporal change in geographic representation. The odds of trial leadership outside Europe and North America were significantly lower with industry versus public funding (OR: 0.33; 95% CI: 0.15 to 0.75; P=0.008). Trial leadership outside Europe and North America was associated with enrolment of patients outside Europe and North America (OR: 10.0; 95% CI 5.6–19.0; P<0.001).
Conclusion
Trial leadership outside Europe and North America is rare, particularly in industry funded trials, and is associated with participant enrolment in regions with disproportionate disease burden. Building research capacity and networks in under-represented regions could increase generalizability of trial results.

Abstract
Rice false smut (RFS) disease, which is caused by Ustilaginoidea virens, has been widespread all over the world in recent years, causing irreversible losses. Under artificial culture conditions, exudates will appear on colonies of U. virens during the growth of the hyphae. Exudation of droplets is a common feature in many fungi, but the functions of exudates are undetermined. As the executors of life functions, proteins can intuitively reflect the functions of exudates. Shotgun proteomics were used in this study. A total of 650 proteins were identified in the exudate of U. virens, and the raw data were made available via ProteomeXchange with the identifier PXD019861. There were 57 subcategories and 167 pathways annotated with Gene Ontology (GO) classification and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, respectively. Through protein–protein interaction (PPI) network analysis, it was found that 20 proteins participated in the biosynthesis of secondary metabolites. Two separate PPI analyses were performed for carbon metabolism and microbial metabolism in diverse environments. After comparing and annotating the functions of proteins of the exudate, it was speculated that the exudate was involved in the construction and remodeling of the fungal cell wall. Pathogenicity, sporulation, and antioxidant effects might all be affected by the exudate.

Abstract
Rhizoctonia solani is an important phytopathogenic fungus with a wide host range and worldwide distribution. The anastomosis group AG1 IA of R. solani has been identified as the predominant causal agent of rice sheath blight, one of the most devastating diseases of crop plants. As a necrotrophic pathogen, R. solani exhibits many characteristics different from biotrophic and hemi-biotrophic pathogens during co-evolutionary interaction with host plants. Various types of secondary metabolites, carbohydrate-active enzymes, secreted proteins and effectors have been revealed to be essential pathogenicity factors in R. solani. Meanwhile, reactive oxygen species, phytohormone signaling, transcription factors and many other defense-associated genes have been identified to contribute to sheath blight resistance in rice. Here, we summarize the recent advances in studies on molecular interactions between rice and R. solani. Based on knowledge of rice-R. solani interactions and sheath blight resistance QTLs, multiple effective strategies have been developed to generate rice cultivars with enhanced sheath blight resistance.

Abstract
Bovine parvovirus (BPV), bovine coronavirus (BCoV) and bovine parainfluenza virus (BPIV) are common etiologies causing gastrointestinal and respiratory diseases in dairy herds. However, there are few reports on the synchronous detection of BPV, BCoV and BPIV. The present article aimed to develop a quick and accurate RT-PCR assay to synchronously detect BPV, BCoV and BPIV based on their specific probes. One pair universal primers, one pair specific primers and one specific probe was designed and synthesized. After the concentrations of primer and probe and annealing temperature were strictly optimized, the specificity, sensitivity and repeatability of the established triplex probe qRT-PCR were evaluated, respectively. The results showed the recombinant plasmids of pMD18-T-BPV, pMD18-T-BCoV and pMD18-T-BPIV were 554bp, 699bp and 704bp, respectively. The optimal annealing temperature was set at 45.0°C for triplex qRT-PCR. The triplex probe qRT-PCR can only synchronously detect BPV, BCoV and BPIV. Detection sensitivities were 2.0×102, 2.0×102 and 2.0×101 copies/μL for BPV, BCoV and BPIV, being 1000-fold greater than that in the conventional PCR. Detection of clinical samples demonstrated that triplex probe qRT-PCR had a higher sensitivity and specificity. The intra-assay and inter-assay coefficient of variation were lower than 2.0%. Clinical specimens verified that the triplex qRT-PCR had a higher sensitivity and specificity than universal PCR. In conclusion, this triplex probe qRT-PCR could detect only BPV, BCoV and BPIV. Minimum detection limits were 2.0×102 copies/μL for BPV and BCoV, and 2.0×101 copies/μL for BPIV. The sensitivity of this triplex probe qRT-PCR was 1000-fold greater than that in the conventional PCR. The newly qRT-PCR could be used to monitor or differentially diagnose virus infection.

Abstract
Abstract
Casestudy: Clear cell sarcoma (CCS), also known as malignant melanoma of soft parts, is a primary soft tissue neoplasm exhibiting evidence of melanocytic differentiation. It is an uncommon aggressive tumor that arises in tendons and aponeuroses of the distal extremities. Here, we report the first case of primary CCS of the breast.
The patient was a 43-year-old female who presented with a left breast mass and underwent surgical resection at an outside hospital. No history of melanoma or any other malignancies was reported. Grossly, it was described as a 2 x 1.5 x 1.5 cm, well-demarcated, white nodular mass. Microscopic examination showed a malignant neoplasm composed of short spindle cells with ill-defined, eosinophilic cytoplasm and ovoid nuclei with finely stippled chromatin and exhibiting moderate pleomorphism. The lesional cells were arranged in short interlacing fascicles with abundant collagen, with brisk mitotic activity (>15/10 HPF). The differential diagnosis included spindle cell carcinoma, myoepithelial carcinoma and melanocytic neoplasm. The tumor cells were immunoreactive for S-100 protein, SOX10, Mart-1, HMB45 and MiTF, but negative for multiple cytokeratins (including high and low molecular weight keratins), p63, EMA, CEA, Caldesmon, smooth muscle myosin, calponin, desmin, ERG, and CD31, thus confirming melanocytic origin. EWSR1 gene rearrangement was detected by fluorescence in situ hybridization analysis using break-apart probes. Overall, the histomorphology combined with the immunophenotype and cytogenetic characteristics, was most consistent with a CCS. To our knowledge, no primary CCS of the breast has been previously reported in the English language literature.

Abstract
Rice false smut (RFS), caused by Ustilaginoidea virens, is one of the most detrimental rice fungal diseases and pose a severe threat to rice production and quality. Effectors in U. virens often act as a set of essential virulence factors that play crucial roles in the interaction between host and the pathogen. Thus, the functions of each effector in U. virens need to be further explored. Here, a conserved small secreted hypersensitive response-inducing protein (hrip) was named UvHrip1. Functional validation was investigated to prove that UvHrip1 suppressed cell death symptom and ROS accumulation in Nicotiana benthamiana triggered by Burkholderia glumae. We performed transgenic technology to demonstrate UvHrip1 remarkably inhibited pathogen-associated molecular pattern-induced defense responses in Arabidopsis seedlings and plants, including the expression of defense-response genes. Furthermore, disease progression caused by the type III secretion system-defective mutant from Pseudomonas syringae pv. tomato DC3000 was strongly facilitated in transgenic Arabidopsis ectopic expressing UvHrip1. Our data demonstrated UvHrip1 suppresses plant innate immunity and promoting disease multiplication in Arabidopsis.

Abstract
OBJECTIVE Lung cancer is the leading cause of cancer death in the world and microRNAs (miRNA) have been found to be involved in the initiation and development of cancer by acting as potential oncogenes or tumor suppressor genes. PATIENTS AND METHODS In this study, we investigated the expression of miR-34b in non-small cell lung cancer (NSCLC) patients and discussed the molecular mechanism of miR-34b in the invasion and migration of A549 cells in vitro. RESULTS Our results showed that miR-34b was significantly down-regulated in primary cancer tissues when compared with the normal lung tissues. The over-expression of miR-34b inhibited migration and invasion, and promoted apoptosis of A549 lung cancer cells. Furthermore, Luciferase reporter assay validated YY1-associated factor 2 (YAF2) as a direct target of miR-34b and YAF2 expression was significantly increased in clinical NSCLC tissue samples. In addition, the over-expression of miR-34b inhibited YAF2, p-Jak2, p-STAT3 and MMP2 protein expression and promoted caspase 3 protein expression in cancer cells. CONCLUSIONS Our results suggest that miR-34b may inhibit migration and invasion of NSCLC cells by targeting YAF2. Thus, our findings provide new insight into the molecular mechanisms of lung cancer metastasis and miR-34b may serve as a potential target in the treatment of human lung cancer.

Abstract
Background Cercospora armoraciae causes leaf spot disease on Armoracia rusticana. Exudation of droplets, when grown on PDA, distinguishes this fungi from other members of the genus Cercospora. The role this exudate plays in the virulence of this pathogen has not been elucidated. To explore this, we characterized the transcriptome of C. armoraciae and the proteome of exudate associated with this plant pathogen. Methods Virulence of three strains of C. armoraciae was evaluated in greenhouse assays. De novo sequencing was applied to assemble transcriptome from these strains. Nano-HPLC-MS/MS analysis was used to identify proteins in the pathogen exudate. Identified proteins were functionally classified and annotated using GO, KEGG, and COG/KOG bioinformatics analysis methods. Results When treated with the exudate of C. armoraciae strain SCa-01, leaves of A. rusticana showed yellowing and necrosis of the leaves and similar symptoms to plants inoculated with this fungi. A total of 14,937 unigenes were assembled from C. armoraciae, and 576 proteins comprising 1,538 peptides, 1,524 unique peptide, were identified from the exudate. GO annotation classified 411 proteins (71%) into 27 functional categories, namely, 12, seven and eight biological process, cellular component, and molecular function subcategories, respectively. KEGG analysis assigned 314 proteins to 84 signaling/metabolic pathways, and 450 proteins were annotated against the COG/KOG database. Discussion Transcriptome and GO analysis of C. armoraciae found most proteins in the exudate. GO analysis suggested that a considerable proportion of proteins were involved in cellular process and metabolic process, which suggests exudates maintain the metabolic balance of this fungi. Some proteins annotated to the phenylalanine metabolism, which suggests that the exudates may enhance the virulence of this pathogen. Some proteins annotated to the phenylalanine metabolism, which suggests that the exudates may enhance the pathogenicity of the pathogen. Also some proteins were annotated to the peroxisome metabolic pathway and the fatty acid biosynthesis pathways. These pathways may confer antifungal, antioxidant and antimicrobial activity on the exudates.

Abstract
BACKGROUND Basal cell carcinoma (BCC) is the most common form of skin carcinoma. AIM To investigate the function of key micro(mi)RNAs and to explore the potential molecular mechanisms involved in BCC. METHODS The microarray dataset GSE34535, which comprises seven BCC samples and seven control samples, was downloaded from the Gene Expression Omnibus database. Differentially expressed miRNAs (DE-miRNAs) were identified. We collected tissue samples from 20 patients with BCC and 20 healthy controls (HCs), to compare the miR-18a expression in their tissue samples. Expression of miR-18a in A431 and HaCaT cells was also assayed. Following this, we upregulated and downregulated miR-18a expression in A431 cells to examine the effects on cell proliferation, migration and apoptosis. To further investigate the relative mechanism, the proteins LC3, Beclin 1, Akt and mammalian target of rapamycin (mTOR) were examined by quantitative real-time PCR and Western blotting. For further verification, we examined the expression of LC3 in the 20 BCC and 20 HC tissue samples. RESULTS In total, 19 DE-miRNAs (13 upregulated and 6 downregulated) that were common to the BCC and HC groups were identified. Levels of miR-18a were about three-fold higher in BCC tissues and A431 cells compared with their respective control groups. In vitro, downregulation of miR-18a was shown to inhibit cell proliferation and activate autophagy via the Akt/mTOR signalling pathway, while upregulation of miR-18a promoted proliferation of these cells. LC3 was decreased in BCC compared with HC tissue samples. CONCLUSIONS Our data support an oncogenic role of miR-18a through a novel Akt/mTOR/Beclin 1/LC3 axis, and suggest that the antitumour effects of miR-18a inhibitor may make it suitable for BCC therapy.

Abstract
Objective: To investigate the efficacy and safety of emergency venous sinus stenting in the treatment of acute visual impairment caused by idiopathic intracranial hypertension (IIH). Methods: A descriptive cross-sectional study design was used to retrospectively analyze 38 patients undergoing venous sinus stenting in the First Affiliated Hospital of Zhengzhou University from January 2013 to October 2019. A total of 9 patients who had sudden short-term vision loss met the inclusion criteria. Routine visual field and fundus examination were performed. The venous sinus stenosis (CVSS) was confirmed by MR venography or DSA. The pressure gradient at both ends of CVSS was ≥10 mmHg(1 mmHg=0.133 kPa). All patients were treated with emergency venous sinus stenting. Six-month follow-up data were collected for comparison, evaluation of the therapeutic effect, and observation of adverse reactions. Results: All 9 patients were successfully treated with venous sinus stent. The pressure gradient at the distal and proximal ends of the stenosis after stent implantation decreased to (2.3±1.2) mmHg. After 6 months of follow-up, the papilledema was significantly improved or disappeared in all patients. The average grade of papilledema decreased from 2.44±0.73 before operation to 0.56±0.53 after treatment (t=6.314, P<0.001). The visual acuity of 9 patients recovered to the pre-onset level or improved significantly after 6 months. The average baseline value of preoperative visual acuity (logMAR) was 0.12±0.11, which increased to 0.74±0.13 on average 6 months after operation (t=-10.827, P<0.001). No recurrence of symptoms or serious adverse reactions occurred in all patients during the follow-up period. Conclusion: For patients with acute visual impairment caused by idiopathic cranial hypertension, emergency venous sinus stenting is a relatively safe and effective treatment that can effectively improve visual acuity.

Abstract
Artesunate (ARS) has been shown to be highly effective against chloroquine-resistant malaria. In vitro studies reported that ARS has anticancer effects; however, its detrimental action on cancer cells may also play a role in its toxicity toward normal cells and its potential toxicity has not been sufficiently researched. In this study, we investigated the possible cytotoxic effects using normal BRL-3A and AML12 liver cells. The results showed that ARS dose-dependently inhibited cell proliferation and arrested the G0/G1 phase cell cycle in both BRL-3A and AML12 liver cells. Western blotting demonstrated that ARS induced a significant downregulation of cyclin-dependent kinase-2 (CDK2), CDK4, cyclin D1, and cyclin E1 in various levels and then caused apoptosis when the Bcl-2/Bax ratio decreased. Conversely, the levels of intracellular reactive oxygen species (ROS) were increased. The ROS scavenger N-acetylcysteine can significantly inhibit cell cycle arrest and apoptosis induced by ARS. Thus, the data confirmed that ARS exposure impairs normal liver cell proliferation by inducing G0/G1 cell cycle arrest and apoptosis, and this detrimental action may be associated with intracellular ROS accumulation. Collectively, the possible side effects of ARS on healthy normal cells cannot be neglected when developing therapies.

Abstract
Rice false smut (RFS), caused by Ustilaginoidea virens, is one of the most detrimental rice fungal diseases and pose a severe threat to rice production and quality. Effectors in U. virens often act as a set of essential virulence factors that play crucial roles in the interaction between host and the pathogen. Thus, the functions of each effector in U. virens need to be further explored. Here, we performed multiple alignment analysis and demonstrated a small secreted hypersensitive response-inducing protein (hrip), named UvHrip1, was highly conserved in fungi. The predicted SP of UvHrip1 was functional, which guided SUC secreted from yeast and was recognized by plant cells. The localization of UvHrip1 was mainly in the nucleus and cytoplasm monitored through the GFP fusion protein in Nicotiana benthamiana cells. uvhrip1 was drastically up-regulated in the susceptible cultivar LYP9 of rice during the pathogen infection, while did not in the resistant cultivar IR28. We also proved that UvHrip1 suppressed the mammalian BAX-induced necrosis-like defense symptoms in N. benthamiana. Furthermore, patterns of expression of defense-related genes, OsPR1#012 and OsPR10b, were regulated over U. virens infection in rice. Collectively, our data demonstrated that infection of U. virens suppresses defense-related genes expression and UvHrip1 was most likely a core effector in regulating plant immunity.

Abstract
Abstract
Introduction
Although the relationships amongst sleep, pain and anxiety have been evidenced, the underlying neurological mechanisms remain elusive. Primary dysmenorrhea is a good model of spontaneous pain with clear painful (menstruation, state) and pain free (e.g., peri-ovulatory phase, trait) conditions. We sought to investigate the state- and trait-related neural signatures that link sleep and anxiety in primary dysmenorrhea.
Methods
Thirty female subjects with primary dysmenorrhea and 30 healthy female controls completed resting-state functional magnetic resonance imaging, the State-Trait Anxiety Inventory and sleep quality assessments during menstruation and peri-ovulatory phases. As we have reported that there was altered default mode network in the primary dysmenorrhea, posterior parietal cortex (PPC) was therefore chosen as the seed to elucidate the functional connectivity that may correlate with sleep and anxiety.
Results
The primary dysmenorrheic subjects exhibited sleep disturbances throughout the menstrual cycle with increased state anxiety. The primary dysmenorrheic subjects demonstrated significantly higher correlations between the sleep quality and the PPC-insula and -putamen functional connectivity during the peri-ovulatory phase. During menstruation, the primary dysmenorrheic subjects demonstrated significantly lower correlations between their state-anxiety scores and the PPC-occipital cortex functional connectivity.
Conclusion
After regressing out the effects of trait anxiety, the correlation between sleep quality and the PPC-putamen functional connectivity was not significant, indicating anxiety-mediated sleep-pain relationship. The PPC-insula functional connectivity, by contrast, was remained significant. Furthermore, state anxiety was associated with the PPC-occipital cortex functional connectivity that was significantly impaired in primary dysmenorrheic subjects. These findings hinted pain and anxiety mediating sleep quality in different neurological circuits.

Abstract
Ustilaginoidea virens, which causes rice false smut (RFS), is one of the most detrimental rice fungal diseases and poses a severe threat to rice production and quality. Effectors in U. virens often act as a group of essential virulence factors that play crucial roles in the interaction between host and the pathogen. Thus, the functions of individual effectors in U. virens need to be further explored. Here, we demonstrated a small secreted hypersensitive response-inducing protein (hrip), named UvHrip1, which was highly conserved in U. virens isolates. UvHrip1 was also proven to suppress necrosis-like defense symptoms in N. benthamiana induced by the oomycete elicitor INF1. The localization of UvHrip1 was mainly in the nuclei and cytoplasm via monitoring the UvHrip1-GFP fusion protein in rice cells. Furthermore, Y2H and BiFC assay demonstrated that UvHrip1 interacted with OsHGW, which is a critical regulator in heading date and grain weight signaling pathways in rice. Expression patterns of defense- and heading date-related genes, OsPR1#051 and OsMYB21, were down-regulated over U. virens infection in rice. Collectively, our data provide a theory for gaining an insight into the molecular mechanisms underlying the UvHrip1 virulence function.

Abstract
Objective: To analyze the clinical characteristics of 2019 novel coronavirus (2019-nCoV) pneumonia and to investigate the correlation between serum inflammatory cytokines and severity of the disease. Methods: 29 patients with 2019-ncov admitted to the isolation ward of Tongji hospital affiliated to Tongji medical college of Huazhong University of Science and Technology in January 2020 were selected as the study subjects. Clinical data were collected and the general information, clinical symptoms, blood test and CT imaging characteristics were analyzed. According to the relevant diagnostic criteria, the patients were divided into three groups: mild (15 cases), severe (9 cases) and critical (5 cases). The expression levels of inflammatory cytokines and other markers in the serum of each group were detected, and the changes of these indicators of the three groups were compared and analyzed, as well as their relationship with the clinical classification of the disease. Results: (1) The main symptoms of 2019-nCoV pneumonia was fever (28/29) with or without respiratory and other systemic symptoms. Two patients died with underlying disease and co-bacterial infection, respectively. (2) The blood test of the patients showed normal or decreased white blood cell count (23/29), decreased lymphocyte count (20/29), increased hypersensitive C reactive protein (hs-CRP) (27/29), and normal procalcitonin. In most patients,serum lactate dehydrogenase (LDH) was significantly increased (20/29), while albumin was decreased(15/29). Alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (Tbil), serum creatinine (Scr) and other items showed no significant changes. (3) CT findings of typical cases were single or multiple patchy ground glass shadows accompanied by septal thickening. When the disease progresses, the lesion increases and the scope expands, and the ground glass shadow coexists with the solid shadow or the stripe shadow. (4) There were statistically significant differences in the expression levels of interleukin-2 receptor (IL-2R) and IL-6 in the serum of the three groups (P<0.05), among which the critical group was higher than the severe group and the severe group was higher than the mildgroup. However, there were no statistically significant differences in serum levels of tumor necrosis factor-alpha (TNF-α), IL-1, IL-8, IL-10, hs-CRP, lymphocyte count and LDH among the three groups (P>0.05). Conclusion: The clinical characteristics of 2019-nCoV pneumonia are similar to those of common viral pneumonia. High resolution CT is of great value in the differential diagnosis of this disease. The increased expression of IL-2R and IL-6 in serum is expected to predict the severity of the 2019-nCoV pneumonia and the prognosis of patients.

Abstract
Objective: To estimate the burden attributed to the dietary inorganic arsenic exposure with lung cancer, bladder cancer and skin cancer as end points. Methods: Inorganic arsenic, food or diet were used as Chinese keywords and arsenic, food and China were used as English keywords to search for literatures related to the dietary inorganic arsenic exposure published by China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform and PubMed Database. Using the data from the China National Nutrition and Health Survey (CNNHS) in 2002 to estimate the dietary inorganic arsenic exposure in Chinese residents. The annual cancer cases attributed to the dietary inorganic arsenic exposure were calculated based on the data from Chinese Cancer Registry Annual Report in 2013. The disability adjusted life year (DALY) was calculated using tools built by WHO. Results: The total DALY of cancer caused by the dietary inorganic arsenic exposure was 419.4 thousand, and the DALY rate was 31.47 per 100 000. The DALY of lung cancer in males and females was 237.7 thousand and 102.5 thousand. The DALY of bladder cancer in males and females was 13.2 thousand and 3.9 thousand. The DALY of skin cancer in males and females was 29.4 thousand and 32.8 thousand. Conclusion: In 2013, the Chinese population had a lower burden of cancer due to the dietary exposure to inorganic arsenic.

Abstract
The present study was aimed to establish a novel TaqMan real-time PCR (RTm-PCR) for detecting and typing bovine viral diarrhea virus (BVDV), and also to develop a diagnostic protocol which simplifies sample collection and processing. Universal primers and TaqMan-MGB probes were designed from the known sequences of conserved 5' - and 3'-untranslated regions (5'UTR, 3'UTR) of the NADL strain of BVDV. Prior to optimizing the assay, cDNAs were transcribed in vitro to make standard curves. The sensitivity, specificity and stability (reproducibility) were evaluated. The RTm-PCR was tested on the 312 feces specimens collected from persistently infected (PI) calves. The results showed the optimum conditions for RTm-PCR were 17.0 μmol/L primer, 7.5 μmol/L probe and 51.4°C annealing temperature. The established TaqMan RTm-PCR assay could specially detect BVDV without detecting any other viruses. Its detection limit was 1.55×100 copies/μL for viral RNA. It was 10000-fold higher than conventional PCR with excellent specificity and reproducibility. 312 samples were tested using this method and universal PCR from six dairy farms, respectively. Positive detections were found in 49 and 44 feces samples, respectively. The occurrence rate was 89.80%. In conclusion, the established TaqMan RTm-PCR could rapidly detect BVDV and effectively identify PI cattle. The detection limit of RTm-PCR was 1.55 copies/μL. It will be beneficial for enhancing diagnosis and therapy efficacy and reduce losses in cattle farms.
